This glitch is minor and doesn't affect any gameplay. I discovered it by reproducing the MCD-4396 bug ("Wrong Game Title on Xbox"). When you do this bug, you can find a new game which appeared as "Minecraft for iOS" for me.
Steps to reproduce:

• Open Minecraft
• Press the Xbox button on the controller.
• Go to the achievements section and select "All achievements".
• Bug (might have been) reproduced.
  If it didn't work, it might have just been for me. There is proof as well, so that you don't think it's fake.
  Edit: it could be because i once played pocket edition on my account
